研究结果表明，漓江为雨源性河流，降雨时空分配极不均匀，70%的降雨量集中在漓江上游区域，全年62.7%降雨量和降雨时间集中在四个月内(即4～7月)，最大的日降雨量可达415.8mm；降雨量最小的月份出现在12月至翌年1月，仅100～110mm，占全年降雨量的6%左右，由此直接影响流域河川径流季节性的变化，造成洪水期和枯水期现象，周期性水量的变化是不为人们意志改变的一种自然规律。

During the infiltration process of indirect subsurface drip irrigation, the ponded water depth changed from zero to a constant and accelerated the water movement in the vertical direction, which reduced the discrepancy of wetted distance in lateral direction and vertical direction, while the changed water depth had small influence on the wetting front movement in vertical direction to upward and downward. The shape of wetted soil zone was spheroid, and its symmetry axis lied near the bottom of the water conducting device.

间接地下滴灌灌水过程中，从零开始逐渐增大并趋于稳定的积水深度加速了水分在垂直方向的运移，缩小了横向湿润距离和垂向湿润距离之间的差异，但变化的积水深度对湿润锋在垂直方向向上和向下的运移速率影响不大，使湿润体形状表现为扁率不断减小的椭球体，且椭球体对称轴分布在靠近导水装置底部的位置。
